So my car is 3 months old, 2012 TL SH-AWD, 6,000km on The car. It sat for about 2 days, without being started. Finally when i went to start it, i had the Battery light come on, "Replace Battery" came on the MID. It only lasted for about 20 sec, then the warning disapeared, and hasn't come on since.

I remember someone else posted something about this issue a while back, but searched and couldn't find the thread.

Is there any cause for concern? Could it be my battery is weak? I'm doing a 10 hr drive next week from Toronto to New York City, and i want to make sure everything is in order. Any insight could help.

Thanks.

 

the battery is under warranty-have the dealer test it. If no problems that 10 hour drive will be a benefit for charging it.

 

Got the same warning this morning. Took my car in to have it looked at since this is about the third time I have received the warning. Tech says that the TL has an overzealous sensor much like that on the MDX's and ZDX's. Acura has a software fix to address the MDX and ZDX issue but not for the TL. Tech suspects that a fix will be forth coming since the issue is now apparent on the TL as well.

 

I notice it in my test drive of the 2012 TL as well. Hopefully I won't see it when I take delivery of my car.

 

I wouldn't worry about it.. until the car doesn't turn over easily.

 

Acura2010, you may want to check out this thread that was started by me as I had the same problem in Calgary:

I never had any issue like this with my 2010 TL, but with my 2012 TL, I have had this a few times already. It must be the new battery management system in the 2012 TL....

 

Thanks, it was your post that i was referencing when i posted this thread. I knew i read it somewhere. What ended up happening to your situation? Did the dealer put in a new battery?

Coming to think of it, i think i may know what caused this issue, and it's probably my fault. I'm a smoker, and always leave my smokes in the car. Never smoke in the car, just leave them in the door. So when the car was parked for a few days, i kept going into my garage and opening the door to get my smokes, which would turn on the headlights everytime. Now over a two day period, of periodic on and off headlights, it's possible it may have drained a little life out of the battery. Those HID's take alot of power. Make sense???

 

Hey Acura2010, I don't think that the fact that you kept opening and closing the door should drain the battery like that!!!

I really think that it's that new "battery management system" that is too sensitive.

I called the dealership and they told me that "30%" of the TL's do that. To me, that is just non-sense. Anyway, I just ignored it because I knew that even if I took it in, they would just give me some ridiculous reason. So far, there really has been no problem again, so I just left it alone....

Now, it would be very interesting if we could do a poll to see what % of the 2012 TL owners have this problem. How do I start a poll???

 

nothing to worry about. it's probably the software error

 

I have seen it once since April and it went away after about a minute. I get more "Tighten Fuel Cap" messages

 

I've gotten that one once too!

 

Oh my, I have gotten that silly tighten fuel cap message once for no reason too!!! It seems like there are several software gremlins with the 2012 TL! LOL

 

My 2012 has the battery light issue as well - if I don't drive it for a few days, or I leave the stereo running in the driveway while I clean/wash/dust/obsess, the light comes on the next time I start it. It always goes away after a drive long enough to charge the battery back up.

 

It clearly seems to be a software issue. My Dealer will let me know if and when a fix is released. As soon as I know, I will share that information here.
